Good point about mature csv's and strange dogs...so many people new to the breed become 'expert(I have only lived with the breed for 4 years)and advise people 'yes,great with other dogs' they are sometimes lulled into false security as they mature late and change a lot,you have to be prepared for a dog that may not mix well,although it seems friends made while young stay forever friends
Also re the 30min jog.... If your dog knows this is the norm they will 'single track' it(use the least but most effcient energy) so self regulate like the husky does....it won't cut it for mental or physical 'tiredness'... You have to be more inventive or at least more varied than that
Your shed may be a penthouse but u don't live in there too
And yes they study you,watch you and learn...one of mine has become an expert at opening the dog gate which u have to squeeze,pull up and push.....all by watching me! And doors? U will need to turn the handles upside down
